Scatter/Gather I/O in Linux: A Deep Dive into readv() and writev() Efficient data transfer is a cornerstone of high-performance systems programming. Linux provides powerful mechanisms to optimize inpu
Linux Kernel Sysfs: Driver-Grade Data Management Example Overview Linux kernel sysfs is often introduced using trivial module parameters or static variables.This project goes beyond that baseline and demonstrates a driver-grade sysfs design built aro...
Building a Linux Kernel Module for Memory and Per-Process RSS via /proc User-space utilities such as top, htop, and free present a polished view of system memory usage, but they abstract away substantial kernel-level mechanics. To understand how Linu...
Creating a production-grade Linux daemon requires more than simply running a program in the background.A correct daemon must detach from the controlling terminal, manage lifecycle files, respond predictably to operating system signals, and clean up a...
1️⃣ Introduction Traversing kernel data structures safely is one of the most common challenges for Linux kernel developers.For example, iterating over all running processes seems straightforward, but the task list may change while you are reading it....
📌 Project: Process Logger & Memory Monitor Kernel Module Project Name: proc_mem_logger This project demonstrates how to write, debug, and safely operate a loadable Linux kernel module that periodically inspects system state from kernel space. The mo...
Writing a Proper Linux Daemon in Swift with Signal Handling Creating a production-grade daemon on Linux requires more than just running a program in the background. A correct implementation must detach from the controlling terminal, manage OS signals...
keys and values are both user-defined maps. so for retrieving a value, key should be provided as an argument of the get() function. The shorthand [key] syntax is also supported. If key is not found, null is returned. There is one more different func...
union() function merge two collections into one. It is in the infix form a union b. Order of the operands is important. In the resulting collection, the elements of the first operand comes before the second: val numbers = setOf("one hundred", "two...
